Change icon for group view

Trying to change the icon for the camera view, if I

group:
  default_view:
    view: yes
    name: bruhswitch
    icon: mdi:home
    entities:
      - switch.fireplace
      - switch.snowman
      - switch.television
      - device_tracker.molly_mollysphone
      - device_tracker.nick_nicksphone
      - light.bedroom
      - light.kids_room
      - light.front_door
      - light.hallway
      - light.dining_room
      - light.kitchen
      - light.kitchen_blooms
      - light.living_room
  Camera:
    view: yes
    name: stupidname
    icon: mdi:camera
    entities:
      - camera.bedroom

this code works, and I get the camera icon, but if I erase the icon line and replace it with:
entity_picture: https://d30y9cdsu7xlg0.cloudfront.net/png/197919-200.png
it gives me errors and messes everything up.
I don’t understand why this is happening?

I am trying to use these alternative svg files as group ‘view’ but It just won’t work.

Does anyone know how to solve this?
